When we think about global warming, our minds often jump to cars, factories, and deforestation. But did you know the digital world is also playing a significant role? 🌡️

Every time you search online, stream a video, send an email, or back up photos to the cloud, you're indirectly adding to the planet’s carbon footprint. Let’s dive deeper into how this happens—and what we can do about it.

How Does the Internet Contribute to Global Warming?

The digital world might seem invisible, but behind the scenes, billions of pieces of information are stored, processed, and transmitted. Here’s what powers it all:

• Data Centres: These massive facilities store and manage the data we create every second. From your social media posts to streaming platforms, data centres keep it all running. But they require enormous amounts of energy—both to power the servers and to cool them.

• Electricity Usage: The energy consumption of data centres globally is staggering, accounting for approximately 1% of the world’s electricity use. Many are still powered by fossil fuels, which release greenhouse gases.

• Digital Overload: The sheer volume of data we create—emails, online searches, video streams, and cloud backups—has led to exponential growth in the demand for energy.

And as our reliance on digital services grows, so does the environmental cost. If data centres were a country, they’d rank among the top energy consumers in the world. 🌍

The Ripple Effect of Digital Habits

• Streaming: Watching an hour of video on platforms like YouTube or Netflix emits approximately 36g of CO₂, the same as driving a small car for 200 metres.

• Email: A single spam email generates about 0.3g of CO₂. While this seems small, multiply it by the billions sent every day, and it adds up fast.

• Cloud Storage: Storing files and photos online means they’re saved on physical servers that consume energy to keep them available 24/7.

Digital convenience comes with a cost, but the good news is we can take meaningful steps to reduce the impact without giving up the benefits.

💡 Solutions: How You Can Help

We’re not suggesting you stop using the internet, but small, mindful changes can collectively make a big difference. Here are practical ways to be part of the solution:

1. Optimise Your Online Activity

• Limit unnecessary searches by bookmarking frequently visited websites.
• Use eco-friendly search engines like Ecosia, which plants trees for every search.

2. Declutter Your Digital Life

• Emails: Unsubscribe from newsletters you never read and delete old emails regularly. Clearing 1GB of storage reduces CO₂ emissions by up to 25kg per year.
• Cloud Storage: Only back up essential files and photos, and review stored data periodically to delete duplicates or unnecessary items.

3. Stream Wisely

• Lower video quality to standard definition for casual watching—it reduces the energy used significantly.
• Download movies or shows you plan to watch multiple times instead of streaming them repeatedly.

4. Support Green Tech

• Choose websites, apps, and services powered by renewable energy. Companies like Google and Apple are investing in carbon-neutral data centres.

5. Advocate for Sustainable Practices

• Encourage businesses and policymakers to invest in renewable energy for powering data centres.
• Spread awareness about the environmental impact of digital habits so others can join the movement.

The Bigger Picture

As the digital world continues to grow, the environmental stakes are higher than ever. By 2030, the carbon emissions from internet usage could double if no action is taken. But it doesn’t have to be this way.

By making small, conscious changes to our digital behaviour, we can collectively reduce the demand for energy-intensive data centres and mitigate their impact on the planet. Every mindful action we take today contributes to a more sustainable future. 💚
